Newly discovered comet Nishimura could be visible to naked eye this weekend

Stargazers in the northern hemisphere get a once-in-437-year chance to observe the comet as it reaches peak visibility just weeks after being identified

A comet called Nishimura discovered just a month ago could be visible to the naked eye this weekend, offering stargazers a once-in-a-437-year chance to observe the celestial visitor.

The ball of rock and ice, whose exact size remains unknown, is named after the Japanese amateur astronomer Hideo Nishimura who first spotted it on 11 August.
